MACHINE FOR CUTTING WINDOW-STILES.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, EDGAR L. ZIEGLER, a citizen of the United States,residing at Jackson, inthe county of Hinds and State of pockets havebeen heretofore cut by maing the circular saws.

chines but only one stile is operated upon at any time and the object ofthis invention is to double the capacity of the machine by constructinga device of this kind which will operate simultaneously and upon a pairof pulley stiles and a further object of the illvention is a machine ofthis kind which can be set to cut pockets of various lengths.

The inventlon consists of a rotatable shaft carrying two circular sawsone above the other, and the reciprocating shafts carrying cross saws,to ether with means for holding in position i u ley stiles upon oppositesides of the circu ar saws when in position to be operated upon bothsides by the cross saw.

In the drawings forming part of this speciiication:-Figure 1 is a planview of my machine. Fig. 2 is a side view. Fig. 3 is a partiallongitudinal section taken through the frame supporting the cuttingdevice, on the line 33 of Fig. 1. Fig. 4 is a section on the line 44 ofFig. 2. Fig. 5 is a detail sectional view showing the manner of mount-Fig. 6 is a detail sectional view showing the manner of holding theinner cross saws.

In these drawings A represents the table of frame -u on which themechanism is mounted anc upon which are two adjustable plates Acentrally cutout as shown at A and set upright parallel to each other.Along the outer sides of these plates are rods B, which extend inadvance of the plates and are held to them by suitable staples. Links Bare pivoted at their outer end to the rear corner ortions of a movablerectangular frame which rests upon the supporting table of frame A. To afront corner of the frame C is pivotally connected a lever D which isslotted as shown at D and is provided with a handle D and a springpressed hand grip D which grip is also provided with a projectingshoulder D between its gripping end and its pivotal point. A link D ispivotally connected to the other forward end of the frame C and isprovided with a suitable pin D which engages the slot D and slidestherein. The forward ends of the rods B are pivotally connectedrespectively to the lever D and to the link D and it will be obviousthat the shifting of the'handle D will spread the rods B or draw themcloser together, accordin to direction of the movement of the handle,thus bringing the plates A the desired distance a art.

A vertical shaft 4 is mounted in the frame and is provided on its lowerportion with a drum E, which is driven by a belt from a drive pulley Emounted on a shaft E carried in suitable bearings at the rear end of thetable A. The shaft E can be driven by any suitable means and I haveshown a handle II to be used where the device is hand operated. In Fig.5 I have shown a detail enlarged view of the upper portion of the shaftE from which it will be seen that this portion is threaded and sleeves Einclose the greater portion of this threaded part being held in place bysuitable nuts E These sleeves serve to support and space two circularsaws E one above the other. This portion of the shaft E extends upwardlybetween the plates A, the saws E being in proper position to cut withthe grain the two long cuts in forming the pulley stile pockets.

To make the cross-cuts at each end of the long cuts the followingmechanism is provided: A shaft F is hung in fixed bearings and a shaft Fis hung in movable bearings F These bearings are moved longitudinallyalong the frame A by means of a threaded rod F operated by a suitablehand wheel F at the front of the machine. The shaft F is provided witha-pulley G, over which runs a belt G which also runs over a pulley Gfixed upon the shaft E. Rotation of the shaft F is conveyed to shaft Fby a train of link gears I'I, thereby permitting adjustment of the shaftF with. respect to the shaft F without throwing the gears of the trainout of mesh with each other. Each of the shafts F and F carry threeupwardly ex tending reciprocating arms J. These arms are pivotallyconnected to plates J which are mounted upon eccentrics J mounted inturn upon the said shafts. At their upper ends the four outer arms Jcarry clamps J in which are held cross-cut saws J. The two inner arms Jwhich extend upwardly bel O O tween the plates A carry each twocross-cut saws J, held in a single clamp, which clamp is shown in detailin Fig. 6 and consists of a flanged U-shaped piece of metal J 6 fittedupon one of the inner arms J and havingaset screw J 7 working throughits bow portion and a plate J 8 bolted to the flanges, the saws beingheld between said plate and the said flanges. The clamp is locked tothearm J, by a wedge J upon which the set screw J 7 bears.

A shaft K is journaled in the frame A and carries a gear wheel K whichmeshes with a rack bar K formed on the under side of a side member ofthe frame 0 and by turning the crank handle K connected to one end ofthe shaft K the frame C and all parts connected thereto including theplates A travel longitudinally upon the frame or table A. To clamp thepulley stiles in position levers L are pivoted at their inner ends independing brackets L and their forward endportions engage suitablestepped rack bars L carried by the forward end portions of the plates A.Rods L pass vertically and loosely through the plates A and have upperthreaded portions upon which are mounted inwardly extending plates Llocked in the proper horizontal plane by means of nuts placed upon eachside of said plates L. These plates project over the pulley stile M tobe operated upon and carry spring plates L which bear upon the upperedges of the stiles and clamp them in position. Each rod is alsoprovided with a coil spring L arranged between the plate A through whichthe rod passes and the plate L supporting the spring It will be obviousthat as the levers L are thrown downwardly at their forward ends theywill draw down the rods L bringing the spring plates L into bindingcontact with the pulley stiles M. These clamp the stiles against anyvertical movement and rear movement is effectively prevented by means ofstops N. Spring clips 0 are also carried b the inner sides of the platesA which p ates are angled to form a track-way for the pulley stiles toslide upon and these spring clips also serve to secure the stiles inplace while being operated upon.

The operation of the device is as follows The stiles M being placed andlocked in position the lever D is brought into position shown in Fig. 1thus bringing the circular saws in position to make the long cuts. Thesaws are driven through the medium of the pulleys, shafts and beltsalready described and by rotating the handle K the stile is fed thedesired length and at the desired speed. When the pin 1) strikes the endof the grip D the saw E has finished its out, and the grip is pressed tothe handle D releasing the pin D. The lever D is then shifted, to throwthe pulley stiles into engagement with the crosscut saws and theoperation is completed. By shifting the lever D inwardly the two innercross-cut saws J of each of the inner arms perform their cuttingoperation upon the inner sides of both the stiles at the same time. Uponshifting of the lever D to its outermost position the stiles are broughtinto engagement with the four outer crosscut saws all of which operateupon the outsides of the stiles simultaneously thus finishing theoperation by three movements, first, the feeding, of the stileslongitudinally by rotation of the shoulder K the bringing them intoengagement with the inner crosscut saws and lastly by throwing them intoengagement with the four outer saws, the last two movements beingaccomplished by proper manipulation of the lever.

In the machine now in use the circular saw is ten inches in diameter andthe inner cross cut saws are six inches in length, thus allowing twoinches at each end of the inner saws for the operation above described.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A device of the kind described comprising a supporting table, a framemovable ongitudinally thereupon, means carried by the frame for holdinga pair of pulley stiles, circular saws adapted to operate upon both ofthe stiles at the same time, a plurality of cross-cut saws, and meansfor successively bringing the inner and outer faces of the pulley stilesinto engagement with the crosscut saws.
